The Samoa Water Authority (SWA) recently chose Innovyze’s H20MAP Water and InfoWorks CS software for water distribution and sewer collection modeling and design of the Samoan network
The SWA is the national supplier of water services to Samoa’s 180,000 citizens. The authority manages five conventional slow-sand filter water treatment plants and five newer rapid-sand filtration package treatment plants. All treated supplies are chlorinated to comply with the Samoa National Drinking Water Standards. Customers served by these treatment plants enjoy safe, quality water on a 24-hour basis if the supply is sufficient. Customers whose water is drawn from springs and river intakes also receive a constant supply, but the water is untreated and not disinfected. Customers served by wells receive intermittent supply determined by the pumping hours of their specific well
H2OMAP Water is a geographic information system (GIS) platform for water utility solutions. As a stand-alone GIS-based program, it combines spatial analysis tools and mapping functions with network modeling for complete infrastructure management and business planning. H2OMAP Water performs comprehensive hydraulic and dynamic water quality modeling, energy management (with true variable speed pumping), real-time simulation and control with online supervisory control and data acquisition (SCADA) interface, and complete fire flow and carbon footprint analyses
H2OMAP Water fully supports geocoding and multiple mapping layers, which can be imported from one of many data sources including computer-aided design (CAD) drawings (e.g., dwg, dgn, dxf); CAD world files; standard GIS formats (Shapefiles, MID/MIF files, and ArcInfo coverages); Vector Product Format (vpf) files; Spatial Database Engine (ArcSDE) layers; attribute tables; grid data; image files; open database connectivity (ODBC); and Comma Separated/Delimited Text (CSV) files. The program also supports the geodatabase standard of ArcGIS through an ArcSDE connection
InfoWorks CS provides wastewater utilities with a tool for undertaking hydrological modeling of the complete urban water cycle. Essential for identifying and justifying cost-effective infrastructure improvements, InfoWorks CS also offers a practical method for operational control (including real-time control) of the sewer network. Other applications include urban flooding and pollution prediction and the modeling of water quality and sediment transport throughout the network
InfoWorks CS features specific tools to support the modeling of subcatchment takeoff and infiltration. With its simulations, the software facilitates the swift modeling of total networks or any subnetwork.
